Finding a good playbook makes my day, if not more than helping out my fellow coaches in any way possible. I just so happen to come across a link to Coach Raymond's 1975 Delaware Blue Hens Playbook!! This playbook has mostly everything we're aware of but may have forgotten about from time to time. Good stuff against various fronts, and play descriptions are brief and self explanatory. Pay attention to the blocking versus a loaded box (or an old school terminology we called a "Gap 8" defense). This will help you out with adjusting to various defensive adjustments and for blocking on air with tackling dummies.
